UUID_TIME

NAME

SYNOPSIS

DESCRIPTION

The
uuid_time
function extracts the time at which the supplied time-based UUID
uu
was created. Note that the UUID creation time is only encoded within
certain types of UUIDs. This function can only reasonably expect to
extract the creation time for UUIDs created with the
uuid_generate_time(3)
function. It may or may not work with UUIDs created by other mechanisms.

RETURN VALUES

The time at which the UUID was created, in seconds since January 1, 1970 GMT
(the epoch), is returned (see
time(2)).
The time at which the UUID was created, in seconds and microseconds since
the epoch, is also stored in the location pointed to by
ret_tv
(see
gettimeofday(2)).
